Xamarin questions

I have a few questions and I'm hoping some people could explain it a bit more.
Recently Xamarin has been released to the public for free and you're able to download/install it for free.
Let me say first that I have Windows 7 and Visual Studio 2015 installed on my computer.
I have succesfully installed Xamarin and the Java/Androids SDKs and got it running.
But now I have the following 'problems':
When opening a new Xamarin Forms project I get the following message:
"A problem was encountered creating the sub project 'Projectname.Windows'. This project requires a Visual Studio update to load. Right-click on the project and choose "Download Update"."
Is this because of my OS?
When opening the new project, the 'ProjectName.UWP (Universal Windows)' subproject always give errormessages on everthing.
Reason?
If I want to run the .IOS subproject, is the only way by connection a IOS device? Is there no emulator for example an Iphone?
Thank you.

It's possible that you don't have the SDK / tooling installed for Windows Phone, so you will have to download the update as described in the error message - this should resolve the problem.
What error messages are you receiving?
You need to connect to a Mac over the network which will allow you to build and debug your apps. You can deploy apps to the iOS Simulator on your Mac, or to an iOS device connected to your Mac, from Visual Studio. For more information on using Xamarin.iOS with Visual Studio, I would suggest the following guide: Introduction to Xamarin.iOS for Visual Studio

Regarding your questions.
1. You should check you updates of the Visual Studio. There are a possibilities that the supporting packages can't locate. The error says that you need to download the updates. Nah, it's not about your OS. If you are done installing the visual studio, then your IDE is working properly. The problem persist is whenever you are lack of updates and packages in the give project.
2. The error could be your pc has no windows emulator to support the UWP to run properly. If you have one, uninstall it and install again.
3. You can use emulator, iOS Emulator but you still need a mac. There's a agreement between microsoft and mac regarding this thing. So far, until now, you can't run iOS simulator in Windows without Mac devices with XCODE
I hope it makes sense.

Answers to your Questions
1. it may be a visual studio update issue, try with latest.
2. i think UWP projects are not supporting with windows 7 OS(correct me if i am wrong), and also try with shared project structure,because portable has some problems with windows 7.
3. Yes currently there is no iOS emulator for Visual studio, if you want to run your app on ios simulator you have to connect your visual studio to Mac machine and then you can run.
Hope this will help

Answering your questions:
1- you might need to upgrade to windows 10. I have solved many issues when I upgraded to Windows 10. VS 2017 works very well with win10.
2- I would definitely recommend downloading the Visual Studio emulator which is a dedicated standalone application that has many emulators. It's much faster and reliable than android emulator. Also it has iPhone and windows emulator too.
3- in order to be able to use iPhone emulator, you must either do:
A) have a Mac device in the network to be able to connect VS with it. And it must have xcode installed on it.
B) you can also do a vmware virtual machine on any windows device and install on it xcode.
For detailed explanation on how tondo the above you can find them on YouTube.
Hope you have more luck.

mt65xx android phone usb drivers

I just need a link to download that driver . I tried everything but I couldn't find. I use windows 10 and everything I found is only for 7/8 . I made an app in android studio and I want to install it on my phone but without this driver is impossible.. thank you

Try using this third party tool called PdaNet. This will automatically install drivers fro your android device.

Android SDK and AVD Manager issue

I am trying to follow the procedure Downloading the Google USB Driver but see the following error in Android SDK and AVD Manager:
Some packages were found but are not
compatible updates.
I am unable to Download the Google USB Driver without the Google Add-ons.
Specifically, I need Google Usb Driver package revision 4 for the Nexus S.
I ran Eclipse > Help > Check for updates but this did not resolve the issue.
Does the Android SDK and AVD Manager need to be updated another way? If so, how?
Is there some other way to fix this?
Does Google Usb Driver package revision 4 work in Windows XP?

That is ok. Those are shown so since they are probably not meant for your version of adt. When you update your android development tools again and check for updates you will be updated to the latest and then you may update to the tools for the latest version. You may still have that alert message since there will also be updates that are not compatible with your your version of adt.

I guess you need to download your latest version (zip file )of adt then install this new .zip file in eclipse.
Then you would be getting the enabled option to download Google USB driver for nexus S.

Which version of the JRE are you running? I had this problem, updated Java, fixed it immediately. I think I was running OpenJava 1.5, upgraded to 1.6 and it worked.

Have you tried running the sdk manager in admin mode, has seemed to help me in the past with strange errors

After completely uninstalling and re-installing the SDK I was able to see and install the Google USB driver but still have been unable to connect the debugger. Perhaps Android development on an Atom based XP Net-Book is a bad idea. I've not been able to get the emulator working so I thought it might be better debugging directly on the target. The emulator just locks up this PC. I've waited up to 40 minutes before giving up. I've had no trouble with Android development on my work PC (emulator or target) but I have some personal projects I'd rather not do on company equipment. Oh well, I probably just need a real PC if I want to work at home.

Issue - I had a working Android Studio and USB driver would allow me to connect to my Huawei Honor 6X mobile device. One day the Android Studio stopped detecting the mobile device and reinstalling Huawei drivers, uninstalling and reinstalling drivers did not work. I tried changing cables and it did not work either. My Windows 8 would not detect the phone when I connected it with USB and Studio did not detect the device either.
Various solutions posted at the forums did not work for me. Finally this is what I did to solve the issue. My LG mobile also works with the Android Studio and I believe this solution will work for all mobile devices and not just Huawei device
Solution -
1) Open Tools> Android > SDK Manager > SDK Tools tab
2) Select Show package details check box
3) Is Google USB Driver selected? Select it if it is not selected, apply & Ok.
3) If Google USB Driver is selected, unselect it and SDK manager will remove the USB drivers.
4) Close Android Studio and follow the above theps and select the Google USB Driver and let studio update the driver
5)Close Android Studio Again
6) Go to Device Manager and you should see 'Android Composite ADB Interface' if the driver is successfully installed
7) That is it, now open Android Studio & when you run the application you should see your mobile device under Connected Devices

Android Application Deployment on LG P500 Device

I am developing the Web application in Android 2.2 and i want to deploy it on the LG P500 device. I am using Windows XP as an operating system. But i am facing the problem of installing the drivers on my system, it gives the error "Hardware not found the desired USB drivers". So give me any suggestion on this.
Also told me that it is possible on windows system or it required Linux System?
Thanks in advance....

There's a similar question about this on Superuser, and the answer appeared to be to download and install the LG Mobile Support Tool, then use it to install the drivers.
As for the second part of your question: Yes, you can develop on Windows. There are versions of the SDK for Windows, Mac and Linux. Most of the tutorials assume you are using Eclipse to develop, which is also cross-platform (as is Netbeans, another popular choice).
If you're looking to build the Android source, however, Windows is not currently supported.
